A coffee filter has the shape of an inverted cone. Water drains out of the filter at a rate 10cm^3/min. When the depth of water in the cone is 8cm, the depth is decreasing at 2cm/min. What is the ratio of the height of the cone to its radius...(adsbygoogle = window.adsbygoogle || []).push({});

I'm stuck with this one.. can anyone help?

BTW.. the answer is 8(squareroot5pi) over 5
